    1. Does this pertain to an incandescent bulb? Probably so. As T is increased, the filament goes from a very dull red to orange then to blue and to white. When it is white light all of the colors of the rainbow are visible if viewed through a dispersing instrument.

    2. ROY G. BIV, a mans name gives the colors from lowest to highest energy.
    red, orange, yellow, green blue indigo, violet. ultra violet is next and infrared precedes the list as the lowest energy.
